"In real life, we weigh the anticipated consequences of the decisions that we are about to make. That approach is much more rational than limiting the percentage of making the error of one kind in an artificial (null hypothesis) setting or using a measure of evidence for each model as the weight."

A recent journal article attempts extending biological evolution from #ML! Here is a stylized diagram of "double descent" by the paper author Steve Frank. The first descent (decrease in error on out-of-sample data) occurs as you add input variables to machine training. Generalization error enhances due to overfitting as you continue. A second descent *may* occur if you add even more input variables to machine training.
